Features

The RS-485 DF1 adapter features the following:

•

The adapter is mounted in and receives power from the PowerFlex drive. Captive screws are used to secure and ground the adapter to the drive.

•

Switches let you set a node address and network data rate before applying power to the PowerFlex drive. Alternatively, you can disable the switches and use parameters to conﬁgure these features.

•

A number of conﬁguration tools can be used to conﬁgure the adapter and connected drive. The tools include the PowerFlex HIM on the drive, or drive-conﬁguration software such as DriveExplorer (version

2.02 or higher) or DriveTools 2000 (version 1.01 or higher).

•

Status indicators report the status of the drive communications, adapter, and network. They are visible both when the cover is opened and when it is closed.

•

Allows DriveExplorer (version 2.02 or higher) to connect to a PowerFlex drive with a 1203-SSS, and “route” out over RS-485 to other PowerFlex drives.

•

Allows an RS-485 DF1 Master device to access the PowerFlex drive:

–

Logic Command/Reference

–

Logic Status Feedback

–

Datalinks A-D

–

Explicit message support

•

User deﬁned fault actions determine how the adapter and PowerFlex drive respond to communication disruptions on the network.

Safety Precautions

Please read the following safety precautions carefully

ATTENTION:

personnel familiar with drive and power products and the associated

machinery should plan or implement the installation, start-up, conﬁguration, and subsequent maintenance of the product using a RS-485 DF1 adapter. Failure to comply may result in injury and/or equipment damage.

ATTENTION:

may contain high voltages that can cause injury or death. Remove all

power from the PowerFlex drive, and then verify power has been removed before installing or removing a RS-485 DF1 adapter.

ATTENTION:

SCANport host products must not be directly connected together via

1202-C* cables. Unpredictable behavior due to timing and other internal procedures can result if two or more devices are connected in this manner.

ATTENTION:

RS-485 DF1 adapter is transmitting control I/O to the drive, the drive

may fault when you reset the adapter. Determine how your drive will respond before resetting an adapter.

ATTENTION: Parameter 10 - [Comm Flt Action]

the adapter and connected PowerFlex drive if communications are disrupted. By default, this parameter faults the PowerFlex drive. You can set this parameter so that the PowerFlex drive continues to run. Precautions should be taken to ensure that the setting of this parameter does not create a risk of injury or equipment damage.

Quick Start

This section is designed to help experienced users conﬁgure or set up the RS-485 DF1 adapter. If you are unsure how to complete a step, refer to the referenced chapter.

Step

1 Review the safety precautions for the adapter.

2 Verify that the PowerFlex drive is properly installed.

3 Commission the adapter.

Set a unique node address and the appropriate data rate using the switches on the adapter. If desired, you can disable the switches and use parameter settings instead.

4 Install the adapter.

Verify that the PowerFlex drive is not powered. Then, connect the adapter to the network using a RS-485 cable and to the drive using the Internal Interface cable. Use the captive screws to secure and ground the adapter to the drive.

5 Apply power to the adapter.

The adapter receives power from the drive and network. Apply power to the network and to the drive. The status indicators should be green. If there is a problem, refer to Chapter

DriveExplorer on the RS-485 Network.

6 Conﬁgure the adapter for your application.

Set the parameters for the following features as required by your application:

•

I/O conﬁguration.

•

Fault actions.

7 Apply power to the RS-485 DF1 master.

Verify that the master and network are installed and functioning in accordance with RS-485 DF1 standards.

Preparing for an Installation

Before installing the RS-485 DF1 adapter:

• Verify that you have all required equipment. Refer to Chapter 1

Getting Started

Commissioning the Adapter

To commission the adapter, you must set a unique node address, the data rate used by the network and the error checking method. (Refer to the

Glossary for details).

Important: New settings are recognized only when power is applied to

the adapter or the adapter is reset. If you change a setting, cycle power or perform a reset.

ATTENTION: Risk of equipment damage exists. The RS-485 DF1 adapter contains ESD (Electrostatic Discharge) sensitive parts that can

be damaged if you do not follow ESD control procedures. Static control precautions are required when handling the adapter. If you are unfamiliar with static control procedures, refer to Guarding Against Electrostatic Damage, Publication 8000-4.5.2.

ATTENTION: Risk of injury or death exists. The PowerFlex drive may contain high voltages that can cause injury or death. Remove

power from the drive, and then verify power has been discharged before installing or removing an adapter.

1. Remove power from the drive.

2. Use static control precautions.

3. Connect an RS-485 cable to the network, and route it through the

bottom of the PowerFlex drive.

4. Connect a 6-pin linear plug to the RS-485 cable.
